Background: This study aimed to determine the diagnostic value of ground-glass opacities on computed tomography combined with computed tomography                         re-examination in patients with suspected novel coronavirus pneumonia. Materials and Methods: Suspected cases of novel coronavirus pneumonia were identified retrospectively between January 23 and February 18, 2020. Computed tomography examination was conducted for all patients. For all suspected cases, real-time reverse transcription-polymerase chain reaction detection of novel coronavirus nucleic acid was conducted. Computed tomography re-examination in the short term was also performed. Results: Among 92 patients suspected with novel coronavirus pneumonia, 15 were diagnosed with coronavirus disease 2019. There were ground-glass opacities on chest computed tomography in 34 patients, and 8 of these patients were confirmed to have novel coronavirus pneumonia. In total, 30 patients showed no absorption on computed tomography re-examination, of which 10 (10/30) were diagnosed with novel coronavirus pneumonia. Additionally, 20 patients had non-absorption of lesions when ground-glass opacities on initial and follow-up computed tomography were combined, and 13 of these patients were confirmed to have novel coronavirus pneumonia. For ground-glass opacities on computed tomography combined with non-absorption of lesions on computed tomography re-examination, the sensitivity and specificity for the diagnosis of the novel coronavirus were 86.7% and 90.1%, respectively. Conclusion: Among suspected patients with novel coronavirus pneumonia, combining ground-glass opacities on computed tomography with a computed tomography re-examination might improve the accuracy of diagnosis.
Keywords: COVID-19, tomography, ground-glass opacities, diagnostic tests.
